Product Details

This high-precision spindle taper hole runout ≤0.001mm, static runout ≤0.005mm, high dynamic accuracy and stability of spindle during machining, effectively ensure the surface smoothness of workpiece.The maximum speed of high efficiency spindle reached 40000rpm, and the material removal rate was significantly improved during processing.Thus, high efficiency processing can be guaranteed.High reliability spindle USES high precision ceramic ball bearing FAG/SKF, bearing before delivery for the full speed section of the spectrum detection, and equipped with a motor temperature control sensor, real-time monitoring spindle processing temperature, ensure the safe operation of the spindle long life.
